Micrometer wrenches are pre-set to the required torque on a vernier scale. An internal spring loaded mechanism measures the torque. When the bolt is tightened to the desired torque it "clicks."
Typically, a pipe wrench is composed of an upper hook jaw and a lower heel jaw, both connected to a flat handle. The lower jaw is adjustable to the size of the metal object. Forward pressure on the handle pulls the jaws closer for ease of gripping and turning. Usually made of aluminum or steel, pipe wrenches are available in various sizes measured by the length of the handle.
A wrench is an invaluable tool for general repair and maintenance. The grip and mechanical advantage it provides enables the user to apply torque to turn nuts and bolts.
Three of the most common wrenches found in American homes are the pipe wrench, the adjustable wrench and the combination wrench.
An automotive tool set should contain a variety of common wrench sizes to handle automotive repairs while on the road. By having a wrench set in your vehicle you are prepared for any emergency car repairs that may be needed.
